I looked over the MIR and it says "Only original refund forms". I'm unsure if this means we can't use a home printed form. To find an answer to that question, I tried calling Sunlight's 1-800 number but they're customer service lines are closed on weekends. Anyone with more experience with mail-in-rebates care to chime in?

I looked over some past mail-in-rebates like the Finish Quantum one and the printable version had the "Only original refund forms" wording. I'm still unsure if the code in the bottom right hand corner is a unique single use code. I will call Sunlight first thing on monday morning and ask. I'll update this thread with information then.

EDIT: The code in the bottom right hand corner is definitely a unique code. Still unsure if it's single use though.
